What you’ll learn

Foundations of the CritiqueExplain why Kant begins by asking what reason can legitimately know.Critique maps reason’s authority instead of simply attacking metaphysics.
The Forms of ExperienceShow how space, time, and self-consciousness condition experience.Experience is structured through intuition and the unity of apperception.
Judgment and the CategoriesTrace how concepts unify a manifold into objects of experience.The categories and schemata connect thought to sensible appearances.
Nature and Its BoundaryDistinguish lawful experience from claims about things in themselves.Kant secures objective nature while limiting speculative reach.
Reason at the LimitDiagnose the paralogisms, antinomies, and ideas of pure reason.Reason seeks completeness, but its ideas guide inquiry rather than become objects of knowledge.
Reading Kant with Kemp SmithRead the Critique as a revised, internally pressured work.Kemp Smith’s commentary preserves tensions and leaves the reader a method.

Questions this course answers

What is Kant's Copernican turn?

Kant argues that space, time, and the categories are conditions under which objects can be experienced, without reducing appearances to private fantasy.

What does transcendental idealism claim about appearances?

Kemp Smith's reading preserves the reality of experienced objects while limiting claims about things as they are in themselves.

Why are the categories objectively valid for Kant?

The categories make coherent, self-conscious experience possible; their validity is transcendental, not an empirical list of observations.

What is the error in the rational-psychological paralogisms?

The “I think” is a condition of self-consciousness, not an intuition that reveals the self as a simple, immortal substance.

What do the antinomies reveal?

Kant uses the conflicts to diagnose reason's illegitimate totalization of conditions that apply within experience.

How should reason use its ideas at the limit of knowledge?

Ideas such as the soul, world, and God can orient inquiry, but theoretical reason cannot constitute them as objects of possible experience.
